Laravel5.1 搭建简单的社区(九)--发表评论

首先创建一个评论控制器:CommentsController,并且添加resource路由:

php artisan make:controller CommentsController
Route::resource('comments', 'CommentsController');

在show.blade.php中展示发表评论界面:

                <hr />
                <!-- 判断用户是否登陆 -->
                @if(\Auth::check())
                    {!! Form::open(['method'=>'post','url'=>'/comments']) !!}
                    <!-- 隐式传递discussion_id -->
                    {!! Form::hidden('discussion_id',$discussion->id) !!}
                    <!--- Body Field --->
                    <div class="form-group">
                        {!! Form::textarea('body', null, ['class' => 'form-control']) !!}
                    </div>
                    <!-- 提交 -->
                    {!! Form::submit('发表评论',['class' => 'btn btn-primary form-control']) !!}
                    {!! Form::close() !!}
                @else
                    <a href="/user/login" class="btn btn-block btn-success">登录发表评论</a>
                @endif

接下来我们定义Request:

php artisan make:request StoreCommentsRequest
    public function rules()
    {
        return [
            // 评论内容非空
            'body' => 'required',
            // discussion_id(隐式传递) 非空
            'discussion_id' => 'required',
        ];
    }

在CommentsController中保存数据:

    public function store(Requests\StoreCommentsRequest $request)
    {
        // 将数据存入数据库
        Comment::create(array_merge($request->all(), ['user_id' => \Auth::user()->id]));
        // 重定向
        return redirect()->action('PostsController@show',['id' => $request->get('discussion_id')]);
    }
